Recently, multi-scale composites have been developed by combining reinforcements from different length scales (macro, micro and nano), in order to overcome the drawbacks of conventional fibre reinforced composites (FRPs), enhance their performances as well as to introduce special functionalities. Most of the current research and development works on multi-scale composites have been focused on carbon based nanomaterials such as carbon nanotubes (CNTs) and nano fibres (CNFs). Looking at the outstanding performance of carbon based multi-scale composites, multi-scale composites based on plant fibres and nano materials are also gaining research attention. Plant fibre based multi-scale composites have been developed either through coating of nano cellulose on plant fibre surface or by dispersing nano/micro cellulosic reinforcements within the matrix of plant fibre composites. This paper provides an overview of recent research studies on multi-scale composites, particularly focusing on plant fibres and cellulosic micro and nanomaterials. Production, processing challenges as well as detailed characterization of mechanical, dynamic-mechanical and thermal properties of these composites have been discussed.
